如何在模式弹出窗口中刷新数据或转发到模式弹出窗口

Question

我的程序是这样的：

我面前有一张桌子，当我单击一行时，桌子打开一个boostrap模式弹出窗口。在模式弹出窗口中，我们可以找到一些值和3个按钮。问题出在这里，当我单击此按钮时，这应该在数据库中搜索一些值并刷新模式弹出窗口。取而代之的是，我在servlet中获取值，并且只能在此行的第一个JSP中返回

request.getServletContext().getRequestDispatcher("/myFirstJSP.jsp").forward(request, response);

此图像是我的模式弹出窗口。主要目的是当我单击“替换”按钮时，它应该在数据库中搜索值并将其显示在右侧的小表中

我的模式弹出窗口的代码
